I made it over to pre-registration earlier and scored my badge. It’s a pretty interesting piece of work by [kingpin]. It’s got 95 SMD leds forming a matrix display. The top and bottom icons on the badge are touch sensitive buttons. It’s got selectable modes, programmable text scrolling, a pre-set POV mode and adjustable scrolling speed.
Update: I started digging through the CD they’re handing out at registration and found the schematics, BOM, layout, everything. I’ll have it posted as soon as it finishes uploading over my evdo connection. The board has provisions for wireless, 3 axis accelerometer, serial interface and it’s using a Freescale QF16 processor. (I tried looking up the chip number earlier, but utterly failed)
Update 2: I’m putting interesting defcon files up here. All the badge info I have is online. I noticed a confidentiality notice on one of the files, I’m assuming that it’s ok to distribute since they’re distributing this freely on the conference CD. If I hear otherwise, I’ll have to pull it.
Luis Miras presented “Other Wireless: New ways of being Pwned”. Instead of common con topics like Bluetooth or WiFi, this dealt with the cheap radios used in wireless keyboards, mice, and things like the wireless remote pictured above. These RX/TX pairs are found in 27MHz, 900MHz, and 2.4GHz versions. The devices all use the same main components: a microcontroller, an EEPROM for storing the serial number, and the transmitter. The dongle is nearly the same only with a receiver.

Billy Hoffman and Bryan Sullivan from SPI Dynamics gave one of the more entertaining talks today. The title is an allusion to peoples willingness to apply new technology before they fully understand it. Instead of laughing at silly web 2.0 developers they decided to build their own AJAXified website by consulting the resources that any programmer would: AJAX books, blogs, and forums. What they ended up with was hackervactations.com… a security hole riddled gem built on good intentions.

[J0hnny]’s at Blackhat and Defcon this year with his talk on “No-Tech Hacking”. It’s a fun talk that boils down to this: loads of information can be gathered using low tech methods. A small digital (or film) camera is ideal for shoulder surfing, identifying weaknesses, and assessing strengths.
The talk is pretty amusing – the commentary on the example shots is priceless. The concept has gone over so well at the cons that [J0hnny] has contributed a chapter to a book on risk management. You can grab a sample chapter here. It looks like he’ll be running his talk at 8pm on Friday at Defcon. From the sample chapter, I’d say that the book should be pretty good. It looks like a good introduction to social engineering and using your wits to defeat obstacles (like corporate security).
